I’m sure I could think of a dozen enhancements (as could you).
But basically, a simple personal task list linked to content found in the Atlassian cloud. I’d like it possible to use a Surface or IPad to write/recognize text, but plain keyboard entry is fine. And that’s it.

Sure, things like duration spent per task, maybe another task type (but things to do, things to remember, things to ask are really all you need). And priority? It’s either hot or not.

Links between tasks would be nice perhaps. And maybe arbitrary HTTP links. But simple is the key here. If one needs complex entry – add a Trello board or Confluence post or Jira Ticket — right?
